| Sumari: | Title screen In this study the effect of high-energy mechanical activation of Ti-Ni powder on the hydrogen interaction has been investigated. High-energy mechanical activation was carried out in a planetary ball mill with an acceleration of 60g. The initial powder has a mixture of phases TiNi (B2) and (B19), Ti[2]Ni, TiNi[3. The lattice parameters of these phases correspond to literature data. It has been shown that after high-energy mechanical activation a quasi-amorphous phase was formed in a powder. The content of crystalline phases decreases from 100% up to 45%, while the content of the quasi-amorphous phase increases accordingly. It was shown that lattice parameters of phases slightly change for 0.3-0.5%. The width of all peaks doesn't significantly changes during the first 10 s of mechanical treatment, but a longer processing time leads to its increase which corresponds to an increase of the defect density. It has been shown that lattice parameters of the TiNi and TiNi[3] almost does not change after hydrogenation of studied powders, while the lattice parameter of Ti[2]Ni increases by 2.5% after hydrogenation; this means that the main interaction of hydrogen in the Ti-Ni system occurs with the Ti[2]Ni phase. It has been shown that lattice parameters of Ti[2]Ni-based phase corresponds to the hydrides Ti[2]NiH[0.5] and Ti[2]NiH[0.8] after 30 and 300 s of mechanical activation. It has been obtained that the time of hydrogenation of 90 min is a critical time after which one can observe changing of lattice parameter of studied powders after treatment. The lattice parameter corresponds to the Ti[2]NiH[0.5] hydride after 180 min of hydrogenation. A possible reason may be oxide films formed on the surface during mechanical activation treatments, which broke at long-time hydrogenation.
